First time posting here (so please be gentle, as I am a relative PHP newbie).
I am building an intranet for our company and one of the things I need to do is to create a form that lists all outstanding sales orders (pulled from our accounting database) and provides a "submit" button beside each one to create the relevant work order.
Here is the code:
<div class="report_column">
<div class="report_header">
<div class="report_column_title" style="width:150px;margin-left:5px">ship date</div>
<div class="report_column_title" style="width:200px">customer</div>
<div class="report_column_title" style="width:140px;text-align:right">item</div>
<div class="report_column_title" style="width:120px;text-align:right">quantity</div>
</div>
<?php
// Open connection
include 'includes/dbconnect.php';
// Perform query
$result = mysqli_query($con,"SELECT * FROM tSalOrdr ORDER BY dtShipDate ASC");
// Retrieve results
while($row = mysqli_fetch_array($result)) {
$order = $row['lId'];
if ($row['bCleared'] == 0) {
$shipdate = substr($row['dtShipDate'], 0,10);
$customer = $row['sName'];
$po = $row['sComment'];
echo '<div class="report_item" style="width:750px";>';
echo '<form class="form" action="index.php?page=form&item=create_work_order" method="POST">';
echo '<div class="report_item_date" style="width:120px">'.$shipdate.'</div>';
echo '<div class="report_item_name" style="width:530px">'.$customer;
echo '<input type="hidden" name="po" value="'.$po.'" />';
echo '<input type="submit" class="submit" style="height: 25px;width:100px;margin:0px;padding:0px;margin:0px" value="work order"/>';
echo '</div>';
$result2 = mysqli_query($con,"SELECT * FROM tSOLine WHERE lSOId=$order ORDER BY sDesc ASC");
while($row = mysqli_fetch_array($result2)) {
if ($row['dRemaining'] <> 0) {
echo '<div class="report_item_details">';
echo '<div class="report_item_item">'.$row['sDesc'].'</div>';
echo '<div class="report_item_quantity">'.$row['dRemaining'].'</div>';
echo '</div>';
}
}
echo '</form>';
echo '</div>';
}
}
// Close connection
mysqli_close($con);
?>
</div>
What happens when I do this is that the first "submit" button will, for some reason, send me back to "index.php". The other buttons will load the correct page, however, they do not POST the required value.
Is there something I am doing wrong or is this something that needs different methodology than what I am currently using? My research on this seems to indicate that perhaps I should use javascript or an array to deal with this, but, having never dealt with either, I am not sure how to proceed. Any pointers would be appreciated.
Thanks.

I've made seventeen other forms with it, so I don't think that it is the problem. I'm hoping that this is just a typo or a logic error on my part.
u can use
<button type='submit' class='' name='' onclick=''>Submit</button>
Try to do onclick. See my example below.
input type="button" name="submit" onclick='location.href="index.php?id=$id"'
AS far as I understand, you are making your forms go to index.php:
echo '<form class="form" action="index.php?page=form&item=create_work_order" method="POST">';
Can you explain what is your expected behavior when a button is pushed?

On the list.php page, I am passing a variable using hidden input method in form.
This form redirects to listd.php where the variable is used to run an SQL query to delete a particular row from the database where the variable==name.
If I print the variable on listd.php before processing SQL query then it is visible but during when query is processed it gives unidentified index error.
The code in listd.php works if I take input from the user on the same page.

It's really not necessary to use two forms to do this, unless this is a very dangerous action. this is also the source of your problem. $k is not preserved on the second postback. Requests are stateless. When you submit the second form, the listd.php script runs again from the start, and the values assigned to variables the last time it ran. This is the normal behaviour of HTTP requests in general.
A single-form version might look like this:
list.php
<?php
//this needs to be before anything else otherwise the redirect might fail due to headers already sent.
session_start();
if(isset($_SESSION['username'])) //corrected to use isset(). Only one test for this is needed.
{
echo "<h2>Welcome ".$_SESSION['username']."!</h2>";
echo "<h3><a href='logout.php'>Logout</a></h3>";
}
else
{
header('location:index.php');
die(); //script needs to die because webcrawlers/bots will ignore the redirect header, and view the rest of the page anyway, without permission. Using die() means the rest of the page never gets output.
}

You do not need listd.php at all.
P.S. A separate hint: I see you are copying the same HTML <head> etc material into every page script. This is not necessary. You can create two files e.g. header.php and footer.php. In header.php you can put the opening <html> and <head> tags right down to <body> and any other enclosing tags necessary for the consistent layout of all your pages. Then in footer.php you can put the equivalent closing tags. And then in all the other pages of your site you can simply write <?php require_once("header.php"); ?> as the first line and <?php require_once("footer.php"); ?> as the last line. Then any changes you need to make to the headers (e.g. new CSS files or something) are automatically applied to all the pages without tedious copy/paste actions. Although I suggested that you remove your second script here, you can do this for any other pages in your site. It's also a good general principle of code re-use which you can apply to all kinds of situations in your future code.
P.P.S. I'd also consider using an up-to-date doctype. The HTML5 doctype declaration is simply <!DOCTYPE html>. This will likely result in more consistent behaviour of the HTML and CSS in your page, and future-proofs your application against deprecation of older doctypes which are no longer in current use.
This fairly simple issue is vexing me. I have an html page laid out with CSS. I have a simple php page that returns the latest record from a mysql site. I need to display this information in the html page in the "leftContent" div.
working 'latest.php' page is:
<?php
/*
Return the latest date and record for the left pane.
*/
include 'ESP8266_dbLogin.php';
$result = mysqli_query($link, "SELECT * FROM `thLog` ORDER BY logID DESC LIMIT 1") or die ("Connection error");
while($row = mysqli_fetch_array($result)) {
echo "Date: " . $row['logDate'] . "<br>";
echo "lightVal: " . $row['lightVal'];
}
mysqli_close($link);
?>
'index.html' code is as follows, with the target DIV of contentLeft for the php variables:
<!DOCTYPE html>
<!-- Basic Layout -->
<html>
<head>
<meta content="text/html; charset=ISO-8859-1" http-equiv="content-type">
<title>Sparks - Monitor</title>
<link rel="stylesheet" type="text/css" href="css/default.css">

</head>
<body>
<div id="wrapper">

<div id="banner">
<div id="bannerLeft">

<div id="bannerRight">

<div id="bannerMain">
<h1>SPARKS Energy Monitor - Home</h1>
</div>
</div>
<div class="content" id="contentLeft">

<p> The current lightVal and date should be here<p>
</div>
<div class="content" id="contentRight">
Generating chart, please wait...
</div>
</div>
</div>
</body>
<html>
Any help is gratefully received on the most efficient way to get the php variables (lightVal) into the html page. I know, stupid question!!
1) Rename your index.html to index.php
2) Replace your target div with your PHP code:
<div class="content" id="contentLeft">
<h2>Current Usage:</h2>
<?php
/*
Return the latest date and record for the left pane.
*/
include 'ESP8266_dbLogin.php';
$result = mysqli_query($link, "SELECT * FROM `thLog` ORDER BY logID DESC LIMIT 1") or die ("Connection error");
while($row = mysqli_fetch_array($result)) {
?>
<p class="dateClass"><?=$row['logDate']?></p>
<p class="lightValClass"><?=$row['lightVal']?></p>
<?
}
mysqli_close($link);
?>
</div>
It should be enough, just call index.php from browser.
I have a webpage and a place to submit data. I made a preview page for this, and whenever a user clicks 'preview' he can see what it would look like. The trouble is whenever they click the back button from the preview all the data is gone. How do I avoid this and keep the data without any very complex solutions?
preview.php
<?php
session_start();
$getTitle = $_POST['title'];
$getEntry = $_POST['entry'];
date_default_timezone_set('UTC');
$getTime = date('D, M jS, o, H:i a e');
$user = $_SESSION['username'];
?>

Maybe add a target="_blank" ? It will open the preview in a new tab.
<input type="button" onclick="previewForm('preview.php')" value="Preview" target="_blank"/>
EDIT: Oups not in the form but on your preview link...
Or something like this : http://www.w3schools.com/tags/att_button_formtarget.asp
I have two DIVs which are floating side by side correctly but after embedding the php code as below, the whole page will not show anything. Even When I remove the php code, the page will not show again. The code below is for the div that floats right.
<div style="float:right;">
<?php
echo "<div>
<head>
<link rel='stylesheet' type='text/css' href='chatbox/style/cb_style.css'>
<script type='text/javascript' src='chatbox/ajax.js'></script>
<script type='text/javascript' src='chatbox/chatbox.js'></script>
</head>
<div>";
?>
<div id="container">
<div id="usersOnLine">
<div style="font-weight:bold;margin-top:35%;">Online Users</div>
<div style="height:82%;">
<?php
if (!empty($friends)) {
foreach ($friends as $friend) {
$friend_name = htmlentities($user['username'], ENT_NOQUOTES);
echo "<span>{$friend_name}</span>";
}
}
?>
</div>
<form method="post" action="">
<input type='text' placeholder='search' style='width:145px;'/><a href='#'><span class='glyphicon glyphicon-search'></span></a>
</form>
</div>
<div id="chat_search">
<un>
</div>
</div>
</div>
<div style="clear:both;"></div>
Since you are adding a <head> element into the DOM, you should remove that surrounding div and head and place that first chunk of php code inside your page's <head> section. The browser is getting confused when you introduce a new <head> element that way.
EDIT: to explain further, with a possible example...
You can add those new stylesheet and js entries into your head by appending them to your header include (assuming you are using an include for your main html header - in this example, we call it "header.php", since that's common)
<?php
$addme = '<link rel="stylesheet" type="text/css" href="chatbox/style/cb_style.css">
<script type="text/javascript" src="chatbox/ajax.js"></script>
<script type="text/javascript" src="chatbox/chatbox.js"></script></head>';
ob_start(); // start a buffer
include("header.php");
$contents = ob_get_contents(); // buffer the contents of header.php
ob_end_clean(); // end & clean the buffer
// replace the closing tag with the added stuff
echo str_replace('</head>', $addme, $contents);
?>
So I am trying to access a certain webpage within my site.
In my index, I use a isset($_GET() parameter to access another page. My code for the index.php is as follows:
<!DOCTYPE html>
<html>
<head>
<?php require ("includes/database.php"); ?>
<title>Offstreams Admin Panel</title>
<link rel="stylesheet" type="text/css" href="styles/admin_body.css" />
<link rel="stylesheet" type="text/css" href="styles/admin_header.css" />
<link rel="stylesheet" type="text/css" href="styles/admin_footer.css" />
<link rel="stylesheet" type="text/css" href="styles/admin_postspace.css" />
</head>
<body>
<header>
<!--Header Info Here -->
</header>
<div class="wrapper">
<div class="sidebar">
<ul>
<li>Post New Band</li>
</ul>
</div>
<article>
<?php
if (isset($_GET['post_new_band'])){
require ("includes/post_new_band.php");
echo "Page accessed";
} else {
echo "Page not accessible.";
}
?>
</article>
</div>
</body>
</html>
I have it echo page not available when "index.php?page" doesn't exist. But when it does exist, such as "index.php?post_new_band" (code below) nothing is posted. The sever and database work, that is for sure. MySQL isn't the problem since I am trying to get the html to work.
Code for "post_new_band.php":
<!DOCTYPE html>
<html>
<head>
<!-- Head Info Goes Here -->
</head>
<body>
<h1>Insert New Band</h1>
<form action='index.php?post_new_band' method='post'>

<input type='submit' name='insert_band' value='Add Band' />
</form>
<?php
if (isset($_POST['post_new_band'])){
$band_name = $_POST['band_name'];
if($band_name==''){
echo "<script>alert ('Please Insert Band Name')</script>";
echo "<script>window.open('index.php?post_new_band','_self')</script>"
} else {
$insert_band_name = "insert into Band (band_name) values ('$band_name')";
$run_band_name = mysql_query("$insert_band_name");

You can only use a request key once - so dont use $_GET['post_new_band'] and $_POST['post_new_band'] in the same request. Change one of the keys.
This is pretty stupid, but it actually turned out to be a syntax error involving semi-colons. *Slap to the face.
